Alexander Hess	50b35a8284	Add CLI script to run tactical forecasting heuristic	2021-02-04 12:05:43 +01:00
Alexander Hess	af82951485	Add `OrderHistory.choose_tactical_model()` - the method implements a heuristic from the first research paper that chooses the most promising forecasting `*Model` based on the average daily demand in a `Pixel` for a given `train_horizon` - adjust the test scenario => `LONG_TRAIN_HORIZON` becomes `8` as that is part of the rule implemented in the heuristic	2021-02-02 11:29:27 +01:00
Alexander Hess	4b6d92958d	Add functionality for drawing `folium.Map`s - this code is not unit-tested due to the complexity involving interactive `folium.Map`s => visual checks give high confidence	2021-01-26 17:07:50 +01:00
Alexander Hess	b0f2fdde10	Add rpy2 to the dependencies - add a Jupyter notebook that allows to install all project-external dependencies regarding R and R packages - adjust the GitHub Action workflow to also install R and the R packages used within the project - add a `init_r` module that initializes all R packages globally once the `urban_meal_delivery` package is imported	2021-01-11 16:06:58 +01:00
Alexander Hess	d5b3efbca1	Add `aggregate_orders()` function - the function queries the database and aggregates the ad-hoc orders by pixel and time steps into a demand time series - implement "heavy" integration tests for `aggregate_orders()` - make `pandas` a package dependency - streamline the `Config`	2021-01-07 23:35:13 +01:00
Alexander Hess	54ff377579	Add CLI script to gridify all cities - reorganize `urban_meal_delivery.console` into a sub-package - move `tests.db.conftest` fixtures into `tests.conftest` => some integration tests regarding CLI scripts need a database - add `urban_meal_delivery.console.decorators.db_revision` decorator to ensure the database is at a certain state before a CLI script runs - refactor the `urban_meal_delivery.db.grids.Grid.gridify()` constructor: - bug fix: even empty `Pixel`s end up in the database temporarily => create `Pixel` objects only if an `Address` is to be assigned to it - streamline code and docstring - add further test cases	2021-01-06 16:17:05 +01:00
Alexander Hess	2e3ccd14d5	Use globals for the database connection - remove the factory functions for creating engines and sessions - define global engine, connection, and session objects to be used everywhere in the urban_meal_delivery package	2021-01-04 20:23:55 +01:00
Alexander Hess	3e0300cb0e	Disable too-few-public-methods error in pylint	2020-12-16 11:04:43 +01:00
Alexander Hess	c1064673aa	Isolate configuration related code better - create the global `config` object inside the `urban_meal_delivery.configuration` module - streamline documentation and comments	2020-12-14 15:15:08 +01:00
Alexander Hess	9ee9c04a69	Remove python-dotenv from the dependencies zsh-dotenv automatically loads the environment variables upon entering the project's root.	2020-12-14 14:26:12 +01:00
Alexander Hess	a16c260543	Add database migrations - use Alembic to migrate the PostgreSQL database + create initial migration script to set up the database, as an alternative to db.Base.metadata.create_all() + integrate Alembic into the test suite; the db_engine fixture now has two modes: * create the latest version of tables all at once * invoke `alembic upgrade head` => the "e2e" tests are all run twice, once in each mode; this ensures that the migration scripts re-create the same database schema as db.Base.metadata.create_all() would * in both modes, a temporary PostgreSQL schema is used to create the tables in => could now run "e2e" tests against production database and still have isolation - make the configuration module public (to be used by Alembic) - adjust linting rules for Alembic	2020-08-11 10:29:58 +02:00
